Description

本発明は、車両のフロントアクスル又はリアアクスルに連結され、車両を駆動するための横置型単一動力源車両用駆動アセンブリに関する。 The present invention relates to a lateral single power source vehicle drive assembly for driving a vehicle, which is connected to a front axle or a rear axle of the vehicle.

現在の純粋な電気自動車又はハイブリッド新エネルギー自動車では、これらに用いられる電動モータの動力特性と車両全体の要求とに開きがあるので、変速比及びトルクの要求を満たすことができない。新エネルギー自動車はますます複雑になる運転状況や道路状況に対応する必要があるので、新エネルギー自動車の快適性及び航続距離に対するユーザの要求が高まり続けており、単純な電動モータ直接駆動モード、電動モータに減速機を接続したモード又は燃料−電気ハイブリッドモードの新エネルギー自動車では、新エネルギー自動車産業の発展要求を満たすことができない。 In current pure electric vehicles or hybrid new energy vehicles, there is a gap between the power characteristics of the electric motors used for them and the requirements of the vehicle as a whole, so that the requirements for the gear ratio and the torque cannot be met. As new energy vehicles have to deal with increasingly complex driving and road conditions, user demands for comfort and cruising range of new energy vehicles continue to increase. A new energy vehicle in a mode in which a speed reducer is connected to a motor or a fuel-electric hybrid mode cannot meet the development requirements of the new energy vehicle industry.

現在の車両の動力アセンブリにおいて、動力源、クラッチ、ギアボックス又は減速機、及び、駆動軸は、通常、縦方向に配置されているため、前後方向に長く、車両空間の多くを占め、コンパクトな構造を必要とする小型車両には適していない。 In current vehicle power assemblies, the power source, clutch, gearbox or speed reducer, and drive shaft are typically arranged in the longitudinal direction, so that they are long in the front-rear direction, occupy most of the vehicle space, and are compact. Not suitable for small vehicles that require construction.

なお、現在、純粋な電気自動車又はハイブリッド新エネルギー自動車では、減速機が電動モータのロータ軸に大きな影響を与え（ロータ軸と入力軸とが一体化されていない）、従来の摩擦クラッチを使用することができず、これらに用いられたクラッチがハード接続という方式しか採用できず、緩衝機能を有していないため、新エネルギー自動車の要求を満たすことができない。 At present, in a pure electric vehicle or a hybrid new energy vehicle, the reduction gear greatly affects the rotor shaft of the electric motor (the rotor shaft and the input shaft are not integrated), and the conventional friction clutch is used. However, since the clutches used for these can only adopt a system of hard connection and do not have a buffering function, the demand of the new energy vehicle cannot be satisfied.

従来の電動モータ直接駆動モードの自動車において、動力系にはクラッチ機能がないので、従来の慣性摩擦シンクロナイザを使用することができず、変速機をシフトすることができず、単一の変速比だけしか使用できない。車両全体の発進及び停止は、電動モータの始動及び停止のみに依存するため、電動モータの性能に影響を与えてしまう。 In a conventional electric motor direct drive mode vehicle, because the power system does not have a clutch function, the conventional inertia friction synchronizer cannot be used, the transmission cannot be shifted, and only a single gear ratio is available. Can only be used. Since starting and stopping of the entire vehicle depends only on starting and stopping of the electric motor, the performance of the electric motor is affected.

先行技術における上記問題に鑑みて、本発明は、従来の動力アセンブリが単一の変速比で伝動し、複雑な道路状況や運転状況に適応できないという問題を解決するための横置型単一動力源車両用駆動アセンブリを提供する。 In view of the above problems in the prior art, the present invention provides a horizontal single power source for solving the problem that the conventional power assembly transmits at a single transmission ratio and cannot adapt to complicated road and driving situations. A drive assembly for a vehicle is provided.

同時に、従来の動力アセンブリの縦寸法が大きいためコンパクト車に使用できないという問題、及び、変速機のギア数が多くて伝動構造が複雑であるという問題を解決する。 At the same time, it solves the problem that the conventional power assembly cannot be used in a compact vehicle due to its large vertical dimension, and the problem that the transmission has a large number of gears and the transmission structure is complicated.

本発明による車両用動力アセンブリは、車両のリアアクスルハーフシャフト又はフロントアクスルハーフシャフトに連結され、車両用動力アセンブリは、２つの変速比での伝動を実現することができる。伝動方式は柔軟性を有し、さまざまな道路状況での車両全体の運転ニーズが満たされる。車両が重い負荷で坂を登っている場合には、大きい変速比での伝動を選択して、車両全体の駆動力を向上させ、車両全体の駆動力不足という欠陥を補うことができる。車両全体が巡航している場合には、小さい変速比での伝動を選択して、車両全体の高速運転要求を満たし、エネルギーを節約し、車両の航続距離を向上させることができる。 The advantages of the present invention arranged using the above structure are as follows.
The vehicle power assembly according to the present invention is connected to a rear axle half shaft or a front axle half shaft of a vehicle, and the vehicle power assembly can realize transmission at two gear ratios. The transmission system is flexible and meets the driving needs of the entire vehicle in different road conditions. When the vehicle is climbing a hill with a heavy load, it is possible to select transmission with a large gear ratio to improve the driving force of the entire vehicle and compensate for the defect of insufficient driving force of the entire vehicle. When the entire vehicle is cruising, transmission with a smaller gear ratio can be selected to meet the high speed driving requirements of the entire vehicle, conserve energy and improve vehicle range.

図１に示すように、本発明の実施例１において、横置型単一動力源車両用駆動アセンブリは、アクスルハーフシャフトに連結され、この車両用駆動アセンブリは、動力源と自動変速機１０とを含み、自動変速機１０に入力軸２０が設けられ、動力源が入力軸２０に連結され、自動変速機１０とアクスルハーフシャフトとの連結箇所に差動装置５０が設けられている。 As shown in FIG. 1, in Embodiment 1 of the present invention, a horizontal single power source vehicle drive assembly is connected to an axle half shaft, and the vehicle drive assembly includes a power source and an automatic transmission 10. Including, the input shaft 20 is provided to the automatic transmission 10, the power source is connected to the input shaft 20, and the differential device 50 is provided at the connection portion between the automatic transmission 10 and the axle half shaft.

本発明の実施例１において、動力源は、電動モータ７０であり、電動モータ７０のロータ軸と入力軸２０とが一体になっている。 In the first embodiment of the present invention, the power source is the electric motor 70, and the rotor shaft of the electric motor 70 and the input shaft 20 are integrated.

自動変速機１０において、第一の中間軸３１が入力軸と平行に設けられ、第二の中間軸３２が入力軸２０と同軸心方向に設けられ、第三の中間軸３３が第一の中間軸３１と同軸心方向に設けられ、第一のクラッチ４１が第一の中間軸３１と第三の中間軸３３との間に設けられ、第二のクラッチ４２が入力軸と第二の中間軸３２との間に設けられている。 In the automatic transmission 10, the first intermediate shaft 31 is provided parallel to the input shaft, the second intermediate shaft 32 is provided coaxially with the input shaft 20, and the third intermediate shaft 33 is the first intermediate shaft. The first clutch 41 is provided coaxially with the shaft 31, the first clutch 41 is provided between the first intermediate shaft 31 and the third intermediate shaft 33, and the second clutch 42 is provided with the input shaft and the second intermediate shaft. It is provided between 32 and 32.

入力軸２０に第一のギア１１が設けられ、第一の中間軸３１に第二のギア１２が設けられ、第一のギア１１が第二のギア１２と噛合伝動する。第二の中間軸３２に第三のギア１３が設けられ、第三の中間軸３３に第四のギア１４が設けられ、第三のギア１３が第四のギア１４と噛合伝動する。第三の中間軸３３に第五のギア１５が更に設けられ、差動装置５０に第六のギア１６が設けられ、第五のギア１５が第六のギア１６と噛合伝動する。 The input shaft 20 is provided with the first gear 11, the first intermediate shaft 31 is provided with the second gear 12, and the first gear 11 is meshed with the second gear 12. The second intermediate shaft 32 is provided with the third gear 13, the third intermediate shaft 33 is provided with the fourth gear 14, and the third gear 13 is meshed with the fourth gear 14. A fifth gear 15 is further provided on the third intermediate shaft 33, a sixth gear 16 is provided on the differential device 50, and the fifth gear 15 meshes with the sixth gear 16.

上記から分かるように、本発明の実施例１による車両用駆動アセンブリの変速機は、従来の変速機の入力軸、中間軸及び出力軸のレイアウト方式とは異なり、駆動アセンブリの縦寸法を短くすることでコンパクト車に適していると共に、使用されるギア数が少ないので、伝動過程が簡素化されている。 As can be seen from the above, the transmission of the vehicle drive assembly according to the first embodiment of the present invention shortens the vertical dimension of the drive assembly unlike the layout method of the input shaft, the intermediate shaft, and the output shaft of the conventional transmission. This makes it suitable for compact cars and simplifies the transmission process because it uses less gears.

上記駆動アセンブリの動力伝達方式は、次の通りである。 The power transmission method of the drive assembly is as follows.

第一のクラッチ４１が噛み合うと、動力源は、動力を、入力軸２０、第一のギア１１、第二のギア１２、第一の中間軸３１、第三の中間軸３３、第五のギア１５、第六のギア１６及び差動装置５０を順次経由させてアクスルハーフシャフトに伝達する。第一のギア１１と第二のギア１２との噛合伝動比をｉ１とし、第五のギア１５と第六のギア１６との噛合伝動比をｉ３とすると、第一のクラッチ４１が噛み合っている場合、自動変速機１０における噛合伝動比はｉ１×ｉ３となる。これは、第１の運転状況である。 When the first clutch 41 is engaged, the power source supplies power to the input shaft 20, the first gear 11, the second gear 12, the first intermediate shaft 31, the third intermediate shaft 33, and the fifth gear. 15, the sixth gear 16, and the differential device 50 are sequentially transmitted to the axle half shaft. When the meshing transmission ratio between the first gear 11 and the second gear 12 is i1 and the meshing transmission ratio between the fifth gear 15 and the sixth gear 16 is i3, the first clutch 41 is meshed. In this case, the mesh transmission ratio in the automatic transmission 10 is i1×i3. This is the first driving situation.

第二のクラッチ４２が噛み合うと、動力源は、動力を、入力軸２０、第二の中間軸３２、第三のギア１３、第四のギア１４、第三の中間軸３３、第五のギア１５、第六のギア１６及び差動装置５０を順次経由させてアクスルハーフシャフトに伝達する。第三のギア１３と第四のギア１４との噛合伝動比をｉ２とし、第五のギア１５と第六のギア１６との噛合伝動比をｉ３とすると、第二のクラッチ４２が噛み合っている場合、自動変速機１０における噛合伝動比はｉ２×ｉ３となる。これは、第２の運転状況である。 When the second clutch 42 is engaged, the power source supplies power to the input shaft 20, the second intermediate shaft 32, the third gear 13, the fourth gear 14, the third intermediate shaft 33, and the fifth gear. 15, the sixth gear 16, and the differential device 50 are sequentially transmitted to the axle half shaft. When the meshing transmission ratio between the third gear 13 and the fourth gear 14 is i2 and the meshing transmission ratio between the fifth gear 15 and the sixth gear 16 is i3, the second clutch 42 is meshed. In this case, the mesh transmission ratio in the automatic transmission 10 is i2×i3. This is the second driving situation.

第一のクラッチ４１と第二のクラッチ４２とが共に切り離されると、ニュートラル状態になる。 When both the first clutch 41 and the second clutch 42 are disengaged, the neutral state is established.

そのうち、伝動比ｉ１、ｉ２、ｉ３の大きさは、ギアの寸法や歯数を変えることで変更可能であり、これにより、自動変速機１０の伝動比を変更することができる。 Among them, the sizes of the transmission ratios i1, i2, i3 can be changed by changing the size and the number of teeth of the gear, and thus the transmission ratio of the automatic transmission 10 can be changed.

上記から分かるように、当該車両用駆動アセンブリは、２つの変速比での伝動を実現することができる。自動変速機は、制御戦略プログラムに従って、２段速の電子制御オートシフトを実現することができる。伝動方式は柔軟性を有しており、さまざまな道路状況での車両全体の運転ニーズが満たされる。車両が重い負荷で坂を登っている場合には、大きい変速比での伝動を選択して、車両全体の駆動力を向上させ、車両全体の駆動力不足という欠陥を補うことができる。車両全体が巡航している場合には、小さい変速比での伝動を選択して、車両全体の高速運転要求を満たし、エネルギーを節約し、車両の航続距離を向上させることができる。 As can be seen from the above, the vehicle drive assembly is capable of achieving transmission at two gear ratios. The automatic transmission can realize a two-speed electronically controlled automatic shift according to the control strategy program. The transmission system is flexible enough to meet the driving needs of the entire vehicle in different road conditions. When the vehicle is climbing a hill with a heavy load, it is possible to select transmission with a large gear ratio to improve the driving force of the entire vehicle and compensate for the defect of insufficient driving force of the entire vehicle. When the entire vehicle is cruising, transmission with a smaller gear ratio can be selected to meet the high speed driving requirements of the entire vehicle, conserve energy and improve vehicle range.

第一のクラッチ４１及び第二のクラッチ４２は、端面歯クラッチであり、噛合伝動する可動ギアプレートと固定ギアプレートとを含む。可動ギアプレートには、端面伝動歯又は端面歯溝が設けられ、これに対応するように、固定ギアプレートに端面歯溝又は端面伝動歯が設けられている。端面歯クラッチは、摩擦クラッチと比較して、運動エネルギー損失を最大限に低減することが可能であり、電動モータのパワーショックに耐えることができないために寿命が短すぎるという従来の摩擦クラッチの欠点を補うことができる。 The first clutch 41 and the second clutch 42 are end surface toothed clutches, and include a movable gear plate and a fixed gear plate that mesh and transmit. The movable gear plate is provided with end surface transmission teeth or end surface tooth grooves, and correspondingly, the fixed gear plate is provided with end surface tooth grooves or end surface transmission teeth. Compared with friction clutches, end face tooth clutches can reduce kinetic energy loss to the maximum extent, and have the drawback that conventional friction clutches have too short a life because they cannot withstand the power shock of electric motors. Can be supplemented.

端面歯クラッチの駆動方式は、可動ギアプレートが軸方向に移動して固定ギアプレートと噛み合うように駆動されるものであれば、電磁駆動式（電磁吸着による駆動）、油圧駆動式（油圧機構による駆動）、空圧駆動式（空圧機構による駆動）、電気駆動式（電動モータによる駆動）のいずれであってもよい。 As for the drive system of the end surface tooth clutch, as long as the movable gear plate is driven so as to move in the axial direction and mesh with the fixed gear plate, it is an electromagnetic drive type (drive by electromagnetic attraction) or a hydraulic drive type (by a hydraulic mechanism). Driving), pneumatic driving (driving by a pneumatic mechanism), or electric driving (driving by an electric motor).

第一のクラッチ４１及び第二のクラッチ４２が電磁ドグクラッチである場合、車両用駆動アセンブリが動力入力状態にあるとき、電磁ドグクラッチによって、動力と車両全体とをいつでも瞬時に切り離したり結合したりすることができるので、動力の円滑な切換えが達成され、車両の走行安定性が向上する。 When the first clutch 41 and the second clutch 42 are electromagnetic dog clutches, when the vehicle drive assembly is in the power input state, the electromagnetic dog clutch instantly disconnects or couples the power and the entire vehicle at any time. As a result, smooth switching of power is achieved and the running stability of the vehicle is improved.

本発明の実施例１において、アクスルハーフシャフトがフロントアクスルハーフシャフト又はリアアクスルハーフシャフトである。車両用駆動アセンブリがフロントアクスルハーフシャフトに連結されている場合は車両が前輪駆動モードとなり、車両用駆動アセンブリがリアアクスルハーフシャフトに連結されている場合は車両が後輪駆動モードとなる。 In Example 1 of the present invention, the axle half shaft is a front axle half shaft or a rear axle half shaft. The vehicle is in front wheel drive mode when the vehicle drive assembly is connected to the front axle half shaft, and is in the rear wheel drive mode when the vehicle drive assembly is connected to the rear axle half shaft.

本発明の実施例２において、図２に示すように、動力源は、エンジン６１とＩＳＧモータ６２とを組み合わせたものであり、エンジンのアイドル損失や公害を抑制することができると共に、ＩＳＧモータが発電機として機能するので、電力を回生して、エネルギーを回収し、省エネルギー効果を実現することができる。
本発明の実施例２の他の内容は、実施例１と同じであり、ここで繰り返して説明しない。 In the second embodiment of the present invention, as shown in FIG. 2, the power source is a combination of an engine 61 and an ISG motor 62, which can suppress idle loss and pollution of the engine, and Since it functions as a generator, it can regenerate electric power, recover energy, and realize an energy saving effect.
The other contents of the second embodiment of the present invention are the same as those of the first embodiment and will not be repeatedly described here.

本発明の実施例３において、図２に示すように、エンジン６１とＩＳＧモータ６２との間にねじり振動ダンパー６３が設けられている。このねじり振動ダンパー６３は、緩衝機能を有し、エンジンとＩＳＧモータとの接合部のねじり剛性を抑制することで、ねじり振動の固有振動数を低下させ、ねじり振動を低減するものである。
本発明の実施例３の他の内容は、実施例１と同じであり、ここで繰り返して説明しない。 In the third embodiment of the present invention, as shown in FIG. 2, a torsional vibration damper 63 is provided between the engine 61 and the ISG motor 62.

The other contents of the third embodiment of the present invention are the same as those of the first embodiment and will not be repeatedly described here.
